Devil's Due G.I. Joe vs Transformers continuity
Gears was among the dormant Transformers found by Cobra and reprogrammed to be under their control. In the process, he and Brawn were rebuilt to transform into Flight Pods. The two may have participated in an attack on the SPS Research Facility, or it may have just been two regular Flight Pods. When Wheeljack hacked Cobra's computers and undid his comrades' reprogramming, Gears and Brawn hunted down Cobra Commander and blew up the ship he was going to escape from Cobra Island with. However, before the Autobots could capture the commander, they were taken out by Storm Shadow's S.N.A.K.E. mech.
Gears didn't give up so easily, however, as he joined several other Autobots and located Cobra Commander and his S.N.A.K.E. guards again. Storm Shadow fought back and killed Trailbreaker, sending Gears and the others into a berserker rage as they ripped his S.N.A.K.E. apart.
